SMD LED vs. COB LED: Hagaha Isbarbardhigga

Tiknoolajiyada LED-ku waxay wax ka beddeshay iftiinka iyo bandhigyada adduunka, iyada oo bixisa xalal tamar-ku-ool ah iyo xalal kala duwan. Laba ka mid ah noocyada ugu caansan ee tignoolajiyada LED waa SMD (Aaladda Dusha-Dusha) LEDs iyo COB (Chip-on-Board) LEDs. In kasta oo labaduba ay leeyihiin faa'iidooyinkooda iyo codsiyadooda gaarka ah, fahamka farqiga u dhexeeya ayaa kaa caawin kara inaad doorato tignoolajiyada saxda ah ee LED baahidaada.

Waa maxay SMD LED?
Aaladda Dusha-Dusha (SMD) LEDs ayaa si toos ah loogu dhejiyaa dusha sare ee looxa wareegga. Waxaa si weyn loogu isticmaalaa codsiyo kala duwan, laga bilaabo bandhigyada LED ilaa iftiinka guud. SMD LEDs waxaa lagu yaqaan hufnaantooda, dabacsanaantooda, iyo fududaynta rakibidda.

Astaamaha muhiimka ah ee SMD LEDs:

Kala duwanaansho: LED-yada SMD waxay ku yimaadaan cabbirro iyo qaabeyn kala duwan, taasoo ka dhigaysa inay ku habboon yihiin codsiyo badan oo kala duwan, oo ay ku jiraan bandhigyada, nalalka, iyo tilmaamayaasha.
Iftiin: Waxay bixiyaan heerar dhalaal sare leh, taasoo ka dhigaysa mid ku habboon codsiyada halka muuqaalku muhiim yahay.
Ikhtiyaarada Midabka: SMD LEDs waxay soo saari karaan midabyo badan iyagoo isku daraya casaanka, cagaarka, iyo buluugga ee hal xirmo.
Kuleylka kuleylka: SMD LEDs waxay leeyihiin sifooyin kulaylka wanaagsan oo ay ugu wacan tahay naqshadooda, taas oo ka caawisa ilaalinta waxqabadka iyo cimri dhererka.
Waa maxay COB LED?
Chip-on-Board (COB) LED-yada waxaa ka mid ah in si toos ah loogu dhejiyo jajabyo badan oo LED ah oo lagu dhejiyo substrate si ay u sameeyaan hal cutub. Habkani wuxuu kor u qaadayaa guud ahaan soosaarka iftiinka iyo waxtarka. COB LEDs waxaa caadi ahaan loo adeegsadaa codsiyada iftiinka sare leh sida nalalka daadka, nalalka hoose, iyo nalka sare-sare.

Astaamaha muhiimka ah ee COB LEDs:

Soosaarka Lumen Sare: COB LEDs waxay bixiyaan wax soo saar sare oo lumen ah halkii inch oo labajibbaaran marka la barbar dhigo SMD LEDs, taasoo ka dhigaysa mid ku habboon codsiyada iftiinka xoogga leh.
Iftiinka lebbiska ah: Naqshadeynta COB LEDs waxay keentaa iftiin isku mid ah oo leh dhibco kulul oo yar, abuurista khibrad iftiin fudud.
Naqshad is haysta: COB LEDs waa is haysta waxayna ku haboonaan karaan qalabyo yaryar, taas oo u oggolaanaysa naqshado nalal badan oo la hagaajiyay.
Waxtarka Tamarta: COB LEDs aad bay u tamar fiican yihiin, waxayna bixiyaan iftiin badan iyagoo isticmaalaya awood yar.
Isbarbardhigga SMD iyo COB LEDs
Soo-saarka iftiinka:

SMD LEDs: Bixi iftiin dhalaalaya oo ku habboon codsiyada kala duwan, laakiin waxaa laga yaabaa inay soo saaraan iftiin badan oo kala firdhisan.
COB LEDs: Waxay bixiyaan soo saarid iftiin badan oo isku dhafan oo isku mid ah, oo ku habboon iftiinka xoogga badan.
Maareynta kulaylka:

SMD LEDs: Guud ahaan waxay leeyihiin kuleyl wanaagsan oo kuleyl ah sababtoo ah kala soocida LED-yada gaarka ah.
COB LEDs: Waxay u baahan yihiin xalal maarayn kulayl oo hufan sababtoo ah xoogga sare ee LED-yada aag yar.
Codsiyada:

SMD LEDs: Wax badan oo si weyn loogu isticmaalo bandhigyada, nalka guriga, calaamadaha, iyo iftiinka baabuurta.
COB LEDs: Sida ugu fiican ee loogu talagalay codsiyada u baahan wax soo saarka lumen sare iyo iftiin isku mid ah, sida nalalka warshadaha, nalalka wadooyinka, iyo nalalka sare-sare.
Dabacsanaanta Naqshadeynta:

SMD LEDs: Waxay bixiyaan dabacsanaan badan oo naqshadeynta ah sababtoo ah helitaankooda cabbirro iyo qaabayn kala duwan.
COB LEDs: In badan oo is haysta laakiin waxa laga yaabaa inay u baahdaan qalabyo gaar ah si ay u habeeyaan naqshadooda.
Gabagabo
Labada SMD iyo COB LEDs labaduba waxay leeyihiin awooddooda gaarka ah waxayna ku habboon yihiin codsiyo kala duwan. Haddii aad u baahan tahay xalal nalal badan oo dabacsan oo leh xulashooyin midabyo badan, SMD LEDs ayaa ah habka loo maro. Dhanka kale, haddii aad u baahan tahay xoog-sare, nalal isku mid ah oo leh naqshad is haysta, COB LEDs ayaa ah doorashada ugu fiican. Fahamka kala duwanaanshahan ayaa kaa caawin doona inaad samayso go'aan xog ogaal ah oo aad u wanaajiso iftiinkaaga ama soo bandhig xalalka waxqabadka iyo hufnaanta ugu fiican.
